GAS-G EN ERATOR.

SPECIFICATION forming part or' Letters Patent No. 694,288, datedFebruary 25, 1902. Application filed November 11, 1899. Serial No.736,606. (No model.)

To all whom, t may concern:

Be it known that I, RUDOLPH A. KUMMER, of the city of St. Louis, Stateof Missouri, have invented certain new and useful Improvements inGas-Generators, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention consists ofthe novel construc tion, combination, andarrangementof parts hereinafter shown, described, and claimed.

The object of this invention is to construct a device for generating gasfrom gasolene and which may be used for lamps or gasolenestoves.

' Figure 1 is a side View of my complete generator, shown used with anordinary Welsbach burner. Fig. 2 is a vertical sectional view. Fig. 3'is a horizontal sectional view taken on the line a d of Fig. 2.

In the construction of the device, as shown, I provide a metallic ring1, having an integral projection2, containing a socket 3. The inner faceof the ring 1 is provided with a circular groove 4. In this ring 1 isfitted a generator tube 5, provided with an annular groove 6 incommunication with the groove 4, formed in the ring 1, thereby producinga chamber to receive oil or gas generated from the oil. Saidgenerator-tube 5 is provided with a plurality of jet-apertures 7,extending therethrough and communicating with the grooves 4 and 6.Mounted in the generatortube 5 and extending above it is a mixingtube 8,which may be of any desirable length and is provided with a plurality ofslots 9 for the entrance of air to mix with the rising gas within saidmixing-tube, which is delivered to the burner 10. Within thegenerator-tube 5, immediately above the jet-apertures 7, I place anipple 11, extended vertically a short distance, and in'the nipple issuspended a metallic pendant 12. This pendant serves to restrict thepassage-way in the nipple 11, so as to retard the flow of air into theopen lower end of the nipple, and thus prevent the commingling ofsufficient air with the gas to cause complete combustion within thegenerator.

Within the socket 3 is a pipe 13, to the upper end of which thevalve-housing 14 is connected. The valve-housing receives the connectionof a gasolene-supply pipe 15, and the valve is operated by the stem 16of ordinary construction, provided at its end with a needle 17 forcontrolling the passage ofthe gasolene into the pipe 13. Said stem 16 isprovided With the hand-wheel 18, and on the stem is placed a stop 19 tolimit the rotation of the valve-stein and regulate the flow of gasoleuepast the valve 17 into the pipe 13. This is done by means of the stop19when said valve is open coming in contact with the pipe 15 andpreventing said valve from being further opened. Within the socket 3beneath the pipe 15 is placed filtering material Y2O, through which thegas or gasolene must pass before being allowed to pass through theaperture 21, communicating with said socket and grooves 4 and 6, therebyfiltering the gasolene and talring therefrom all foreign substance andalso preventing the clogging of said aperture 21.

As shown in Fig. 1, my generator may be used With an ordinary Welsbachburner. ,It may also be applied to a stove, in which use it is obviouslynecessary to construct it of larger form.

The operation of the device is as follows: The pipe 15 is connected withan ordinary gasolene-supply tank and gasolene is allowed to pass intothe valve-housing 14 when the valve 17 is unseated. The gasolene isallowed to pass the valve 17 into the'pipe 18 and through the filteringmaterial 2O and the aperture 21 into the space formed by the grooves 4and 6 and then through the pluthe nipple 11. The gasolene is thenignited and by reason of the jet-apertures 7 being of small diameterjets of blue iiame are produced that strike the pendant 12. The gasolenewhich escapes through the apertures 7 is immediately generated into gas.The jets being located Within the burner and at a point above the lowerextremity thereof, there is no opportunity for a sufficient mixing ofoxygen with the jets for complete combustion, and the result is that theunconsumed vapor readily ascends through the mixingtube to the burnervat the upper end thereof. The burner is then lighted,and while the sameis continually burning the gasolene escaping through the jet-apertures 7also burns continually. By the continuous burning of the gas in thegenerator at the jet-apertures 7 the rality of jet-apertures 7 into theinterior of IOO pendant, ring, and nipple become very, hot and thegasolene entering the space formed by the grooves 4 and 6 is constantlyconverted into gas.

I claim as my inventionl. A device of the class described, comprising agenerator-tube open at its lower end for the entrance of air, an oil andgas chamber having jet-apertures leading therefrom into the interior ofthe generator-tube above the lower extremity thereof, a mixing-tubesnrmounting said generator, a burner located at the upper end of saidmixing-tube, and means for partly closing the lumen of thegeneratortube, substantially as described.

2. A device of the class described comprising a generator-lube open atits lower end for the entrance of air and containing an oil and gas.chamber having jet-apertures leading therefrom into the interior of thegeneratortube above the lower extremity thereof, a nipple located withinsaid generator-tube above said jet-apertures, a mixing-tube surmountingsaid generator-tube, and a burner located at the upper end of saidmixing-tube, substantially as described.

3. The combination of a ring having an inner annular groove, agenerator-tube having an annular groove positioned opposite the groovein said ring, said generator-tube being provided with apertures leadingfrom said grooves to the interior of the generator-tube, means throughwhich gasolene is conducted to said grooves, a nipple, a pendant, and amixing-tube carrying a burner, substantially as described.

4. A gas-generator comprising a ring provided with an annular groove, ageneratortube carried by said ring, and having apertures communicatingwith said groove,a pendant suspended Within said generator .tube, and amixing-tube.

5. A gas-generator comprising a ring provided With-a groove, andapertures, a generator-tube placed in said ring, and having a groovecommunicating with the groove in said ring, the apertures formed throughsaid gencrater-tube communicating with both of said grooves, a nipplemounted within the generator-tube and positioned immediately above saidapertures, a pendant suspended Within the nipple, a mixing-tube mountedupon said generator-tube and communicating with the burner, a valvemechanism communicating With said ring, and means for regulating the Howof fuel Within said ring.

In testimony whereof I affix my signature` in presence of two witnesses,
